  • Adaptive control of an electronic imaging camera
    Patent number: 5185671
    Abstract: A CCD imaging camera is adaptively controlled by: illuminating a reflectance field of view, selectively sensing a desired image field area within the field of view and generating an image signal thereof, reducing low frequency components of the sensed area image signal, generating a contrast signal from the image signal, generating an average or mean signal from a plurality of image contrast signals, comparing the mean signal with a reference signal corresponding to a predetermined contrast maximum value, and thereafter controlling the light level or the range of the camera to the object field.
